1. An apparatus for warning a pedestrian of a vehicle, comprising:
- a sensor configured to sense a position of a pedestrian in a vicinity of the vehicle;
a pair of dipole speakers installed to be spaced apart within an engine compartment of a vehicle at a predetermined distance from each other; and
a control unit configured to transmit a warning sound signal to the pair of dipole speakers and control a phase, a frequency, and a volume of a sound signal transmitted to each of the pair of dipole speakers based on positional information of the pedestrian calculated by the control unit.

Abstract
Disclosed is a system for warning a pedestrian of an oncoming vehicle. In particular, a sensor senses the position of a pedestrian in the vicinity of a vehicle. The position information is then sent to a control unit which controls a phase, a frequency, and a volume of a sound signal transmitted to a pair of dipole speakers based on positional information of the pedestrian calculated by the control unit.

8. A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:
-
program instructions that dynamically control a phase, a frequency, and a volume of a warning sound signal transmitted to a pair of dipole speakers based a distance and an angle between the pedestrian and the vehicle calculated by the control unit; program instructions that dynamically control an orientation angle of each dipole speaker based upon the distance and angle between the pedestrian and the vehicle; and program instructions that transmit the warning sound signal to the pair of dipole speakers based upon the distance and angle between the pedestrian and the vehicle.
